Spatiotemporal patterns of rain-on-snow and basal ice in high Arctic Svalbard: detection of a climate-cryosphere regime shift
Peeters, Bart; Pedersen, Åshild Ønvik; Loe, Leif Egil; Isaksen, Ketil; Veiberg, Vebjørn; Stien, Audun; Kohler, Jack; gallet, jean-charles; Aanes, Ronny; Hansen, Brage Bremset (Journal article; Peer reviewed, 2018)Arctic winters have become increasingly warmer and rainier. Where permafrost prevails, winter rain (or rain-on-snow; ROS) is known to occasionally cause extensive ice layers at the snow/ground interface, i.e. "basal ice" ... -
Towards rainy Arctic winters: effects of experimental icing on tundra plants and their soil conditions
Le Moullec, Mathilde; Isaksen, Ketil; Petit Bon, Matteo; Jónsdóttir, Ingibjörg Svala; Varpe, Øystein; Hendel, Anna-Lena; Beumer, Larissa Teresa; Hansen, Brage Bremset (MET report;, Research report, 2019)Global warming comes with more frequent extreme climate events. In the Arctic, extreme warm spells with heavy rain-on-snow events in winter can cause dramatic changes to the snow-pack and encapsulate the vegetation in thick ... -
Warmer and wetter winters: characteristics and implications of an extreme weather event in the High Arctic
Hansen, Brage Bremset; Isaksen, Ketil; Benestad, Rasmus E.; Kohler, Jack; Pedersen, Åshild Ø.; Loe, Leif Egil; Coulson, Stephen James; Larsen, Jan Otto; Varpe, Øystein (Journal article; Peer reviewed, 2014)One predicted consequence of global warming is an increased frequency of extreme weather events, such as heat waves, droughts, or heavy rainfalls. In parts of the Arctic, extreme warm spells and heavy rain-on-snow (ROS) ...
